Help! Installing a 24v TM on a '93 Pro V.

[cornstalk]

Hello board:<br /><br />Hopefully someone can set me straight on this. I recently purchased a '93 pro v, and would like to install my 24v minnkota on the bow. I have purchased the batteries, and dropped them under the deck,....and now I'm stumped. <br /><br />I have a total of six 8 ga wires coming into my battery compartment: A long red and a long black which reach the port side battery, A short red and a short black, which reach the starboard battery. The last two wires are both orange, and are coiled up in a roll and taped up. (As though they werent previously used)<br /><br />I also have four much smaller wires coming into the compartment, (Long red, long black, short red, short black). I believe these are for the battery condition meter. (Battery 1 and battery 2). <br /><br />I have purchased a "Rig Right" plug containing the internal jumper, and have wired this to my trolling motor using the orange wire, and the black wire.<br /><br />Can anyone tell me what I need to do next within my battery compartment? Can I just hook my four red/black wires up to each individual battery..along with my condition meter wires, and be good to go? Or do I need to somehow involve the orange wires?<br /><br />Thanks for any help on this.

I can't tell you what all those wires are for but I can tell you what is needed for the trolling motor. First, run a heavy jumper from the pos side of one bat to the neg side of the other. Then connect the neg lead from the TM to the neg lug with nothing on it and the pos lead to the other battery's lug with nothing on it. If you can verify that 2 of the 6 gauge wires go straight to the TM, you can use them.

Lots of questions need to be asked and here goes:<br />1. What power wires (colors) do you have coming from the trolling motor?<br />2. Where do you want those trolling motor wires to go. a) a connector panel at the bow, or b) directly to the batteries.<br />3) Is the motor capable of both 12V and 24V operation?<br />4) If the answer to #3 is yes -- is voltage controlled at the a) the connector panel or b) on the motor itself.<br />4) Is the battery condition meter for one, two, or three batteries and what are the wire colors.<br />5) What is the Rig Right deal with the internal jumper? What does it accomplish.<br />6) Do you know how to get the batteries themselves wired for 24V (disregarding connecting anything to them).<br />7) Are there any other 12V accessories that will be connected to these batteries?<br /><br />Sorry about all the questions, but we can't see your boat. We don't know what you have that's stock, or what's been added previously.

Thanks for the responce:<br /><br />I'll try to answer your questions as best I can.<br /><br />1. I have a pos and a neg wire coming from my 24v 62lb minnkota AP. The pos wire on the troll motor is connected to the orange wire on a Rig Rite V-groove plug, and the black wire is connected to the black wire on the V-groove plug. I think we're ok here.<br /><br />2. The plug then goes to a receptical plug at the bow. This receptical plug has three wires leading out of it....an orange, a red, and a black.<br /><br />3. Motor is a 24v.<br />4. The battery condition meter wires are red/black and red/black --- 4 wires.<br />5. Rig Rite is a common name brand plug sold for this very purpose. Supposed to be able to put the batteries in series within the plug itself.<br />6. My biggest confusion here is which wires to use, whether I have the correct wires.<br />7. I will have an Eagle graph running off this system eventually.<br /><br />I did determine why I have double sets of wires. (6 total 8 ga wires) One set (red,orange, black for the front recep...and the pro v also has a receptical in the back..thus the additional 3 wires. I wont be using the rear recep at this point. Just want to get 24v to the bow, and be able to splice off 12v for the bowmount graph.<br /><br />thanks

OK -- we can move on from here. The reason you have red, orange and black wires from the receptacle is that some 24V trollers were capable of running on 12V. I won't go into that because it will likely raise more questions. So -ignore the orange wire as it won't be used. If you have the red and black wires from the troller mating with the red and black wires on the Rig-Right that part is good. The two batteries are wired as follows: BAT 1 POS goes to the red wire to the Rig-Right connector. BAT 1 NEG goes to BAT 2 POS using a jumper wire. BAT 2 NEG goes to the black wire on the Rig-Right connector. Your motor should now run. Each red/black pair of wires from the condition meter connects to the respective POS & NEG terminals on BAT 1 and BAT 2. Make sure you don't mix the pairs (such as BAT 1 POS and BAT 2 NEG). Your 12V accessories can be connected to either of the two batteries. Be sure to include a circuit breaker/fuse at the BAT 1 POS to protect the trolling motor wiring. You should also protect the accessory feed with appropriate fuses.

Ok....Great, you answered a lot of my questions within that last post. Just a couple of things.<br /><br />I noticed that the rig rite plug I had purchased for my troll motor is actually a 4 hole/ 3 wires (red, orange, black) My bow receptical is a 3 prong/wire as stated earlier. So, I went in and picked up a 4 prong rig rite receptical to install at the bow location.<br /><br />My question is...I now have an additional wire coming off the back side of the receptical. Can I install the system as you specify,...and ignore both the orange and the blk/blue stripe wires on the receptical ? Why are these additional two wires in place if I dont need to use them?<br /><br />Secondly, if I set it up as you stated...I would need to run my troll motor red wire, to the red wire on the rig rite plug....and the black troll motor wire to the black rig rite wire? In other words I would be disregarding the orange wire on the rig rite plug? (My rig rite plug has a sticker on it saying to use the orange wire if installing on a 24 system)<br /><br />Concerning my eagle graph......I can simply wire it neg to neg / pos to pos off of say battery #1, and it will be 12v's ?<br /><br />I'm hoping it's just as simple as you stated it above, and that I'm just trying to make it more complicated than it is. Mostly, I dont want to burn up my trolling motor due to improper wiring.<br /><br />Thanks a bunch for the help.<br /><br />P.S. I was told to run a 40 amp breaker off both batteries pos terminals. You mention just running a single breaker off of one of the pos terminals?

It really doesn't matter which wires you use to power the motor as long as you get 24V to the motor through the plug and receptacle. Use red and black since red is universally POSITIVE and black is universally NEGATIVE. As I pointed out, some motors were both 12 and 24V capable. You need three or four wires to do that and there are a couple of ways two batteries are wired to accomplish this. The orange and black/blue wires simply are a second pair to be used to accomplish 12/24V operation. This is why I said I didn't want to get into that scenario as it only results in more questions that most people don't understand the answers to (no offense intended). You do not need a breaker on both terminals. Install one off the POS terminal feeding the receptacle. You NEVER switch or put a breaker in a ground lead.
